ICSF supports the Advanced Encryption Standard (AES) algorithm for data privacy. This provides strong encryption. Data can be encrypted and decrypted using 128-bit, 192-bit, and 256-bit keys. The algorithm has the same availability as triple DES.

AES on a z990, z890, z9 EC, z9 BC, z10 EC, z10 BC, and z196 requires feature 3863, CP Assist for Cryptographic Functions (CPACF) DES/TDES Enablement.
